The female ninja, Ayame, successfully captured the criminal Kamou, who had been kidnapping village girls. However, it was revealed that there was someone behind Kamou, instructing him to carry out the abductions. That person's name was Echigoya, a corrupt merchant. Infiltrating Echigoya's mansion, Ayame disguises herself as a maid to ensnare her target. Using her exceptional skills and her alluring body, she tries to trap Echigoya... or so she thought. It turns out that her opponent is one step ahead. Subjected to lewd restraints, drenched in aphrodisiacs, and facing unexpected torment from Echigoya, Ayame loses control of her rationality. And thus, she meets her ultimate fate... "What happened to you, Ayame-senpai?" The fallen female ninja writhes with an eerie allure. The lustful panting of the female dogs fades away into a white abyss, tainted with breast milk and semen.
